I toyed with both, Cathode on the Mac as well as Cool-retro-term on Linux, for video production. The effect and quality is exactly what I want. My only pain is that they both don't fit well into my workflow. Does anyone know a plugin for Blender or Natron that can produce a high quality realistic CRT effect? Preferably with similar flexibility and parameters as Cathode or Cool-retro-term. All the plugins I found were very limited and most of them didn't even attempt to look realistic. For me quality and realism are key, convenient use in a compositor is also important. I don't care about rendering times. Things I found during my research that look useful and cool but also don't quite fit into a more traditional compositor workflow: * CRT-Royale [1] is a GPU based real-time CRT shader that seems to go into ridiculous detail. * FFmpeg CRT Transform [2] is a purely FFmpeg based CRT effect.

I'm glad to see you're interested in quality and authenticity in your video productions. A lot of major Hollywood studios just don't give a crap, and composite some green text in Courier or Consolas onto a prop. Cool-retro-term is open source, and jwz wrote some modules (like apple2) for xscreensaver that also have a detailed CRT simulation. So maybe mine that code for techniques to include in a blender module?

> Does anyone know a plugin for Blender or Natron that can produce a high quality realistic CRT effect? Sounds like a pretty niche scratch-an-itch thing for somebody to write. If you know Python the Blender Python API isn't that hard to learn, although it does tend to change sometimes, especially between major versions, and sometimes minor versions as well.

Have you looked at shadertoy.com? Searching 'CRT' has about 160 results, some look pretty good though you may have different requirements For example, https://www.shadertoy.com/view/Ms23DR https://www.shadertoy.com/view/Ms23DR

If you can use Adobe Premiere plugins through some means there's a ton of retro & VCR style plugins in their world. Most are commercial but not super expensive. I've used this one and liked it a lot: https://www.maxon.net/en/red-giant-complete/universe/vhs https://www.maxon.net/en/red-giant-complete/universe/vhs There are lots of knobs to tweak and you could definitely get something that's more like cool retro term.

I feel like you could get some real nice CRT effects in blender by messing with shader nodes. I doubt a plugin would add much to that workflow that's not there already natively.
